Nickel is an extremely important metal. Along with chromium, it is one of the most essential of all alloying elements, used in a wide variety of steels, stainless steels, and superalloys. It’s tough, corrosion-resistant and exhibits excellent strength and impact properties.

Nickel and its various alloys tend to work harden during machining. There are several ways to combat this. First, the cutting tool should have a positive rake and sharp edge.

Inconel also has a high tolerance for pressure. Combined with its extreme temperature tolerance, this makes Inconel perfect for a variety of punishing operating environments.Because it is less brittle than carbide, high-speed steel might work well, although the cutting speeds, in this case, must be kept quite low, typically at 100 surface feet per minute or less as a starting point.

Making setups as rigid as possible is good advice for any machining application, but especially so for super-tough metals like nickel and nickel-bearing alloys. For milling operations, a shrink-fit holder is often the first choice, with hydraulic or mechanical milling chucks coming in a close second.

Identifying the specification and grade of the base metal is critical when choosing the right filler metal for a low-alloy steel application. The easiest way to determine minimum requirements is to consult the base material specification.

Your first instinct might be to ease off on the feed and slow down the spindle. Bad idea. All cutting tool manufacturers supply recommended surface speeds, depths of cut and feed rate ranges. When trouble strikes, it’s often a good idea to shoot for the upper end of those parameters and cut more aggressively, not less. 

It is also common with some high-strength low-alloy steel weldments to undermatch, which means the tensile or yield strength of the filler metal is lower than that of the base metal. If a component is designed so that stresses are not concentrated in the welds, undermatching can be a way to maximize weld ductility and fatigue life.

paramount. Trochoidal toolpaths provide consistent chip loads and prevent shock to the cutting tool and workpiece alike. Because nickel-based alloys are tough, stepovers should be well below the radius of the milling tool and feed rates relatively high. Conversely, the minimum depth of cut for turning should be no less than the tool nose radius, and preferably several times that if possible.

Nickel machining is no time for tribal knowledge, second-shift secrets, or uncontrolled process changes. Get documenting. It’s not unheard of for cutting and shaping tools to be broken or deformed when used to shape Inconel. In other cases, the Inconel’s outer layer may harden too quickly in response to machining, resulting in an imperfect shape for the Inconel.
